...And so it begins. The 1.8L dual vvt-i 2zr-fe is a relatively new engine, released in 2007. This engine produces 136hp/129ftlbs at the crank in stock form, and is a smog legal swap when done properly. There is great aftermarket support with people making 150hp n/a with flow mods, or 200hp+ with available superchargers and turbo kits. I chose to get my swap components from a auto recycler instead of buying a scion xd. My engine is from a 2013 Corolla with 34k on the odometer(the valve cover writing is wrong)...a great find. My car is automatic and Ive kept the auto for now to check compatibility. Lets start, here's whats needed:

If you go through a recycler you need to prepare yourself to make a ton of phone calls and be clear about what you need and how you want it. Expect to spend roughly $3000 total for everything needed. You can also buy a entire wrecked car if you like, but it will cost you more. You want everything that was originally attached to the engine, including ecm, exhaust, airbox(xd), passenger engine mount(xd), ect. Ill cover all of this throughout my install.

The first thing I checked was compatibility with the yaris c50 transmission. The 2zr and 1nz flywheels/Flexplates are the same size, the only difference is the 2zr has 8 bolts where the 1nz has 6.....so use the 2zr flywheel and your 1nz clutch.

I ordered the xd airbox, engine mount, and maintenance items today. They should be in tomorrow, now I just gotta get an ecm and start the wiring.

I can help with the wiring diagrams if you have to modify anything--I just snagged copies of every year xD and Yaris that I could find on the Toyota tech site.

On a format note: I'm not sure if the file size is the reason for only one picture per post, but it would be much more helpful to have the whole process in the first few posts instead of having to sort through lots of replies to find the content.

I went through the wiring diagrams today and verified the 2zr ECM(automatic transmission) and harness are mostly plug-n-play with the Yaris U340E. For you guys using a manual transmission, you need a manual trans specific harness and ECM.

Could you clarify a little more on this? What do you mean by U340E?

One of my other concerns is emissions. When you swap to a different car ECM, I'm wondering what kinda of problems that will create when one goes for their annual emissions testing? Doesn't the computer store the VIN info, and I wonder if it will throw a red flag when the emissions testing machine is hooked up to your car, and the VIN #s don't jive?
